I guess you only uploaded the exe file, you needed to archive the whole folder and then upload it here. Sorry, but your game looks like a nice start from the screenshots

Redownloaded and it works, managed to finish in a couple of tries the first level but the second one was too hard for me, maybe reduce the fog a bit since there are also the half platforms that you can collide with and they all look the same in the fog. Could have probably finish that as well but I had to remember the level by hard cause there was no time to react.
